This chip is not found in ChipGuide and I don't have any California books.

Below are some scans from the ChipGuide

This one shows the known $100 with the standard OceanSide back

This one shows the known 25 with the shield back

The differences I see are:
1) Mine has the shield back which isn't seen on the $100 chip in the ChipGuide
2) Mine doesn't have the Commerative tag
3) Mine has a different insert pattern
4) Mine is numbered and I don't see that on any other chips in the ChipGuide

Is this a known variation and just not in the ChipGuide?

Thanks for the help
